Abstract: ABSTRACT    A telescopic control unit for  an atherectomy device to incrementally cut a passageway through obstructive tissue in arteries comprises a cylindrical-shaped hollow housing which has a tube-shaped telescoping insert coaxially aligned within an interior chamber of the housing.  The telescoping insert is held  in  place  with  respect  to  the  housing  by  threadably engaging a ring-shaped cap to the housing which causes an O-ring  to  urge  against  the  insert  and  hold  it  securely  in place.    A  tube-shaped  sheath  or  guiding  catheter  for  an atherectomy  cutter  is  connected to  the  distal  end  of  the insert.   A cutter  assembly comprised of  a torque  tube and cutter is slidably carried inside the guiding catheter.   The torque tube is operably connected to a handpiece drive unit coupled  to the control unit  to  rotatably drive the cutter.          Selective control of telescoping insert incrementally advances the handpiece drive unit, and then the cutter, deeper into the artery.  The obstructive tissue cuttings are removed from the artery by a suction system which is attached at the proximal end of the housing.  The housing device is also equipped with a port for injecting medicinal fluids therethrough to aid in the operation.

Patent CA-2030596-A1 (CA)
Inventor: BRADSHAW JERALD S
IPC: B01J39/26
Filed: 1990-11-23
Abstract: A method is disclosed for the quantitative removal and concentration of desired molecules or ions, such as gases, anions and amino acids, from a source solution which may contain larger concentrations of other molecules. The method comprises bringing the source solution into contact with a solid cation-ligand-matrix consisting of a cation complexed to a ligand molecule covalently bonded to a matrix consisting of an organic spacer bonded to a solid inorganic support through a silicon atom. The cation has an affinity for the desired molecules to form a complex between the desired molecules and the cation portion of the solid cation-ligand-matrix at binding sites initially held by H2O or other weakly coordinated ligands or via ion pairing. The desired molecule complex is broken releasing either the desired molecules or desired molecules complexed with the cation by contacting the solid cation-ligand-matrix-desired molecule complex with a much smaller volume of a receiving solution in which said desired molecules are soluble. The concentrated ions or molecules thus removed may be analyzed and/or recovered by known methods. The process is useful in measuring the concentrations of molecules originally present at parts per billion levels; in the removal of low levels of toxic molecules such as ammonia or anions such as chromate from potable and saline water; in the preparation of ultrapure salts and gases; and in the recovery of valuable molecules present in low concentrations as in the separation of amino acids, etc.

Title: Softening agents for recycling asphalt pavement
Inventor: SAWATZKY HENRY
IPC: C08L95/00
Filed: 1991-01-16
Abstract: Methods and compositions are provided for rejuvenating aged asphaltic paving material, or for improving the compatibility of aged asphalt in salvaged old asphalt paving materials with other asphaltic materials, or of improving the resilience to stripping of rejuvenated asphalt and aggregates, by the use of an agent which was heretofore not known to be a rejuvenating agent. Such rejuvenating agent is a sewage sludge-derived oil, or a fraction thereof, having a particularly recited composition. This rejuvenating agent markedly lowers the viscosity of the aged asphalt, disperses the components of the aged asphaltic paving material for dispersion of such, or other added asphaltic components in the asphalt, and increases the adhesion of aged asphaltic paving material to aggregates. Such rejuvenating agent may be used together with other conventional rejuvenating agents and/or softening agents, e.g., hydrocarbon products with physical characteristics which are selected to restore aged asphalt to the requirement of current asphalt specifications, for example, soft virgin asphalts.
